contained in earlier chapters of this manual.
Topics include:

Using the DOS Directory
Shell
The DOS directory shell allows you to perform a large number of DOS related
tasks while the BASIC development software is still active. Not only does it display
DOS directories and build directory trees from which you can select files, but it is
also a fully integrated file/disk manager with the ability to:
•
display up to four directories at a time, in either full directory display mode or
condensed display mode
•
build a graphic directory tree you can move through and select directories as
the tree builds
•
mark multiple files for copying, deleting, printing or loading, or prompt for a
DOS command to be repeated on all marked files. For example, you can mark
several .BDL files, enter the compiler command at the command prompt, press
[Enter]
, and all marked files are compiled.
•
view or change file attributes
•
view any file in a pop-up, Read-Only window for quick browsing
•
sort directories by name, extension, size, date, and time (ascending or
descending). Multiple sorts are supported. Note that the sorted directory
cannot be stored on disk, but remains sorted for the current editing session. If
the BASIC development software is exited, the next time the directory is
displayed, it appears as it did before the sort.
•
run any DOS command with the touch of a key
•
examine the contents of any .ZIP or .ARC file by simply selecting it
•
run any .EXE, .COM or .BAT file by simply selecting it
